"On Highly Poisonous Agents"

There is a highly toxic drug in the world, called sodium cyanide. Its nature is poisonous, it changes color when smelled, and it is dangerous when touched.

The LD50 of sodium cyanide is the key number to measure its toxicity. LD50 is half the lethal dose. This value is extremely low, which shows its virulence. If you enter the body in a small dose, you will feel uncomfortable, dizzy, nausea and vomiting; in severe cases, the breath is weak, the limbs twitch, and in an instant, your life is at stake.

Looking at all poisons, sodium cyanide is often feared by the world because of its rapid toxicity. It acts on the human body as quickly as electricity, can break the physiological balance of the human body, mess with its qi and blood, and damage its internal organs. If a person accidentally touches it, or inhales its volatile gas, or eats contaminated things by mistake, they may step into the gate of hell.

Therefore, the control of this thing should be strict and strict. Hidden secret rooms are guarded by special personnel, and entry and exit registration must not be slack in the slightest. Everyone should also be aware of its harm and avoid it. Don't risk your life because you don't know it.

Such a highly toxic thing is really a danger in the world, and you must always be vigilant to ensure the well-being of all people.
